Answer:

e. 23.14 m

Step-by-step explanation:

Perimeter of the figure = ½(perimeter of a circle) + 2(a) + b

= ½(πd) + 2(a) + b

Where,

d = 2 m

a = 9 m

b = 2 m

Plug in the values into the equation

Perimeter of the figure = ½(π*2) + 2(9) + 2

= π + 20

= 23.14 m (nearest hundredth)

This question is incomplete, the complete question is;

A general reaction written as A + 2B → C + 2D is studied and yields the following rate law: ∆A/∆t = k A².

The initial concentration is 1.000 M and t½=20.00 s.

How long will it take for the concentration to reach 0.0500 M

Answer:

it will take 380 seconds for the concentration to reach 0.0500 M

Step-by-step explanation:

Given that;

A + 2B → C + 2D

initial concentration A₀ = 1 M

half life t1/2 = 20sec

concentration after t time [A_t] = 0.0500 M

∆A/∆t = k A²

This is a second order chemical kinetics

for this order; t1/2 = 1 / [A]₀K

A₀ is initial concentration, K is rate constant, t1/2 is half life

so,

k = 1 / [A₀]t1/2

we substitute

K = 1 / 1.000 × 20

K = 0.05 mol⁻¹L/sec

for second reaction order

1/[A_t] = kt + 1/[A₀]

kt = 1/[A_t] - 1/[A₀]

we substitute

kt = 1/0.0500 - 1/1.000

kt = 20 - 1

kt = 19

substitute the value of k

0.05 × t = 19

t = 19 / 0.05

t = 380 sec

Therefore it will take 380 seconds for the concentration to reach 0.0500 M

Answer:

(-2/17, 5/17)

Step-by-step explanation:

Given the coordinates A (-3,-5) to B (9,4), we are to find the coordinate of the point cutting the line using the ratio 7:10

Using the midpoint formula;

M(X,Y) = {(ax1+bx2/a+b, (ay1+by2/a+b))

Given

x1 = -3, y1 = -5, x2 = 9, y2 = 4, a = 7 and b = 10

get the required coordinates;

X = ax1+bx2/a+b

X = 7(-3)+10(9)/7+10

X = -21+19/17

X = -2/17

Get the Y coordinate;

Y = ay1+by2/a+b

Y = 7(-5)+10(4)/7+10

Y = -35+40/17

Y = 5/17

Hence the required coordinate is (-2/17, 5/17)

Answer:

150$

Step-by-step explanation:

In order to find the answer to this question you must find twenty-five percent of two-hundred.

50% of 100 = 50

100% of 100 = 100

100% of 200 = 200

50% of 200 = 100

25% of 200 = 150

= 150$

Answer:

$475

Step-by-step explanation:

First, we need to subtract 61 from 1011 which given us 950. Then, we divide 950 by 2 to give us the cost of the dryer :)

950 ÷ 2 = 475

This means the cost of the washer is $536 (not relevant to the answer, but at least now you know :) )

Answer:

-6

Step-by-step explanation:

The value of the given expression will be equal to -3.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The solution to the expression is:-

=  4(  x  +  3  ) (  x + 1  )  /  (  x  +  5  )  (  x  -  5  )

=  4(  3 +  3  ) (  3  + 1  )  /  (  3  +  5  )  (  3  -  5  )

=  (  4  x  6  x  4 )  /  (  8  x   -2  )

=  -3

Therefore the value of the given expression will be equal to -3.

Answer:

£395.

Step-by-step explanation:

Call out fee=35

30 per hour = 2 hour to be =60

but,12 minutes in hours= 12/60= 0.2

0.2 = 0.2*30 = 6

2 hours and 12 minutes would be charge as

30 + 6 = 36

36*10 = 360

call out fee + per hour = 35 + 360 + 395

Answer:

48 minutes

Step-by-step explanation:

First do 3 divided by 3/4 and that gives you 4. Then multiply 4 by 12 and you get 48.

Answer:

45

Step-by-step explanation:

I love math, so this was fun! First, we need to know how long it would take him to walk 1 mile. We know it took 12 minutes to walk 3/4 of a mile, so we just need to figure out how long each quater is. For this problem, each quarter of a mile is 3 minutes, and so we just need to multiply that by 4. then, we know it would take him 15 mintues to walk a mile. Then, just multiply that by 3!

Answer:

Subtration property of Equality

Step-by-step explanation:

B + 7 = 15

   - 7    - 7

B = 8

The equation B + 7 = 15 becomes B = 8 by subtraction property of equality thus option (C) is correct.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use b.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given equation,

B + 7 = 15

Subtract 7 on both sides,

B + 7 - 7 = 15 - 7

B = 8

Hence "The equation B + 7 = 15 becomes B = 8 by subtraction property of equality".

Step-by-step explanation:

Monocots differ from the dicots In the structural features of the leaves, the stems, roots, and flowers. The differences start from the very beginning of the plant's life cycle: the seed. Monocots have one cotyledon, while dicots have two. When it comes to leaves,  monocots have narrow leaves with the typical parallel leaf veins. Dicots have broad leaves with a network of netted leaf veins.

The equation that matches the table is y = -5x + 7 ⇒ C

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope is m =  [tex]\frac{y2-y1}{x2-x1}[/tex] , where

From the given table

→ Choose any two points from the table

∵ Points (0, 7) and (1, 2) are in the table

∴ x1 = 0 and y1 = 7

∴ x2 = 1 and y2 = 2

→ Substitute them in the rule of the slope above

∵ m = [tex]\frac{2-7}{1-0}=\frac{-5}{1}[/tex]

∴ m = -5

→ Substitute it in the form of the equation above

∵ y = -5x + b

∵ b is the value of y at x = 0

∵ At x = 0, y = 7

∴ b = 7

∴ y = -5x + 7

∴ The equation that matches the table is y = -5x + 7
